    MuTeam is a multimicroprocessor system designed to support concurrent programming and decentralised policies for fault treatment. In the paper, the hardware architecture of MuTeam is presented in detail, with particular reference to the innovative solutions adopted to support the above mentioned features. View full abstract»

  • Reed-Muller expansions of incompletely specified functions

    Publication Year: 1987, Page(s):228 - 236
    Cited by:  Papers (11)

    The structure of Reed-Muller and generalised Reed-Muller transform matrices is discussed and in particular their description in terms of the Kronecker matrix product of basic forms is explained. The use of map-entered variables to enable function maps to be folded into smaller-dimension structures, thereby easing the transform process, is investigated. Methods for term-by-term transformation which... View full abstract»

  • Pseudoexhaustively testable ASM-based designs of digital systems

    Publication Year: 1987, Page(s):237 - 242
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (650 KB)

    The concept of pseudoexhaustive testing is combined with that of qualifier preselection to provide easily testable designs of digital systems based on the algorithmic state machine (ASM) method. The highly structured implementations resulting from direct synthesis procedures with modern programmable devices are augmented by the incorporation of a serial shadow state register to provide built-in te...

  • Technical memorandum. Flexible feature detector for binary video images

    Publication Year: 1987, Page(s):243 - 246
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (426 KB)

    The paper describes a real-time feature detector which operates at video rates on binary images. It uses a variant on template matching over a 5 ¿¿ 5 pixel local area. A notable aspect of the detector is its flexibility, allowing the user to define features for detection as required. View full abstract»

  • Pipeline prime-factor DFT for VLSI using cyclic shuffling

    Publication Year: 1987, Page(s):247 - 253
    Cited by:  Papers (6)

    The fast prime-factor discrete Fouriertransform (DFT) algorithm [2¿¿4] can be used to reduce the number of basic cells when the transform length of a DFT is not a highly composite number. This pipeline prime-factor DFT can be realised by a one-to r-dimensional index mapping by (r ¿¿ 1) one-to two-dimensional mappings. Hence, only the one-to two-dimensional shuffling algorithm is needed to realise ... View full abstract»

  • Public-key cryptosystem and digital-signature schemes based on linear algebra over a local ring

    Publication Year: 1987, Page(s):254 - 256
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (293 KB)

    The paper presents a new public-key cryptosystem and new digital-signature schemes. It uses a special matrix over a local ring, the power of which can be easily calculated. It then describes a nonsingular conjugate transformation matrix to get a new matrix as public key. The paper also presents three digital-signature schemes. Their security comes from the problems caused by zero divisors of the l... View full abstract»

  • Fine classification of printed Thai character recognition using the karhunen-loève expansion

    Publication Year: 1987, Page(s):257 - 264
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (844 KB)

    In previous research work, it has been reported that to obtain a high recognition rate in a printed Thai character recognition system, the system should be separated into two stages, namely rough and fine classification stages. In the rough classification stage, eigenvectors of the Karhunen-Lo¿¿ve (K-L) expansion having the maximum eigenvalue are used as the standard patterns of each category of s... View full abstract»
